Bhagavad Gita Doesn't Teach About Renouncing Our Duties

We modern men supposedly have no time to get into the details of the philosophy of Bhagavad-Gita, even in the midst of our ordinary daily duties. But just to teach us, Arjuna pondered the philosophy of Bhagavad-Gita at a time when even a moment seemed impossible to spare i.e. at the the time of war. All this he did for the sake of people like us. But attaining transcendental knowledge doesn't mean renouncing the duties of our ordinary life. After Arjuna had understood the philosophy of Bhagavad-Gita, the Supreme Personality of Godhead, Sri Krsna, never advised him to give up his ordinary duty.
